New to site looking for a part?
 

Hi I was enserch of a part and in my search I came across this site. People with a interest in Chevy trucks. But I had to be a member. ok looking around I see people simply building there truck in there own vision that is great, I have been looking and reading and coming across great information. I have a 81 Chevy step side w/a 250 (4.1) Had it rebuilt, I did not change it because I like the small engine and will probably outlive me now. But I do live in California and I have to deal with smog checks every couple of years, can some point me in the right direction or has one on hand, A Water outlet or sometime called a thermostat housing the lower half, that has a water heater attachment and three connects on the other side one for what looks like a Temp sensor, smog sensor and what ever the third does?
